CALENDAR.

SPECIFICATION forming part of Letters Patent No. 490,618, dated January24, 1893. Application filed April 2, 1892. Serial No. 427,526.(No-model.)

To all whom it may concern:

Be it known that I, JOSEPH WALLIN, a subject of the King of Sweden andNorway, residing at Boston, in the State of Massachusetts, have inventeda new and useful Improvement in Calendars, of which the following is aspecification.

My invention relates to that class of calendars in which revoluble rollsare employed, the positions of which are to be changed every day,andmyinvention consists intheimproved mechanism for operating the rolls, ashereinafter fully set forth.

Figure 1, represents the front view of a calendar embodying myimprovement. Fig. 2, represents a central vertical section taken throughthe outer case, the previously concealed parts being shown in elevation.Fig. 3, represents a vertical section taken in the line 3, 3, of Fig. 1.Fig. 4, represents a vertical section taken in the line 4, 4, of Fig. 2,

. showing the operating bar in its normal position. Fig. 5, representsthe same section with the operating bar in its raised position. Fig. 6,isa detail section showing a portion of the upper roll.

In the accompanyingdrawings,Arepresents the supporting base which may bemade of wood, and B, .B, opposite wooden standards for supporting theseveral rolls, which are arranged one above the other as shown in Fig.3, and over the standards B, B, and the rolls, is placed the cover orcase 0, which is provided with the perforation a, adapted to receive theshank b of the operating bar D,and with the side openings 0, d and e,The consecutive days of the week are marked upon the periphery of a rollE, which turns loosely upon the fixed spindle f, held in the standardsB, B, the said roll being provided with the ratchet wheel g of seventeeth, which ratchet wheel is held in its turned position, by means ofthe spring actuated pawl h, at-

tached to the side of the standard B 5 and the.

roll E is turned for the space of one tooth of the ratchet-wheel g, bymeans of the spring actuated catch 1:, secured in a recess at the sideof the operating bar D, the said bar being held in its normal position,by means of the spring 71, which engages with the projecting lip j, ofthe bar D, the upward movement of the spring i being limited by the stoppin it. The bar D is provided with the slots m, m, adapted to receivethe fixed pins 11., n, which serve to hold the bar in position at theside of the standard B, and may also serve as a stop to its movement, inthe downward direction, against the resilience of the returning springi; and the downward movement of the operating bar D, will serve to turnthe ratchet wheel g, one tooth. The consecutive months of the year aremarked upon the periphery of the roll F, which is arranged to turnloosely upon a fixed spindle 0, held in the standards B, B, the saidroll being provided with the ratchet wheel 19 of twelve teeth, which isheld in its turned position by means of the spring actuated pawl q,attached to the side of the standard B; and the roll F maybe turned forthe space of one twelfth of a revolution by means of the spring catch 1'attached to the recessed inner side of the bar D, which catch will bebrought into action upon a special elevation of the said bar. Theconsecutive numbers for the days of the month, are marked upon a ribbonG, which is attached to the periphery of the two rolls H and I, the rollH being arranged to turn loosely upon the fixed spindle s to which issecured the inner end t of a helical spring a, the outer end beingsecured to the roll H, so that when the ribbon G is being unwound fromthe roll H,

the tension of the spring u will be gradually increased. The ribbon G isunwound from the spring-actuated roll H, by means of the roll I, whichturns loosely upon the fixed spindle o, and is provided with the ratchetwheel 20 of seven teeth, the said ratchet wheel being held in its turnedposition, by means of the spring-actuated pawl 41:, pivoted to thestandard B at the point y, and provided with a disengaging arm a, whichby engagement with the lip a, of the bar D, upon the special upwardmovement of said bar above its normal position, as shown in Fig. 5, willcause the disengagement of the said pawl from the teeth of the wheel w,the spring a, of the pawl x being made to rest against the fixed pin(1'; and the said wheel to and roll I, will be turned for the space ofone tooth upon the downward movement of the bar D, by means of thespring actuated catch Z2, which is secured in a recess made in the sideof the said bar.

The operation of the calendar will be as follows: The operating bar Dbeing first raised as shown in Fig. 5, so that the pawl x will be thrownout of engagement with the ratchet wheel w, the spring 11. will serve towind the r1bbon Gr upon the roll H, so that the figure 1, will appear atthe opening (Z, thus indicating the first day of the month. The rolls Eand F are then to be properly set, so that the proper day of the weekwill be indicated at the opening 0, and the proper month of the year atthe opening 6; then each consecutive downward movement of the bar D, dayafter day, w1ll serve to indicate the day of the week, and the day ofthe month, at the openings 0 and d; and at the end of the month, uponraising the bar D above its normal position, as shown in Fig. 5, thepawl x will be raised from the wheel 20, and the spring a will cause theroll H to turn, and unwind the ribbon G from the roll I, so that thefigure 1 will be again presented at the opening (Z to commence the newmonth, and in the meantime, the said extra upward movement of theoperating bar D, will have caused the turning of the roll F, so as toindicate the new month at the opening 6.

I am aware that it is not new to construct acalendar having an outercase provided with the several openings, and with rolls, which areseparately operated by means of distinct ratchet movements; but in myinvention the several rolls are operated collectively from a single bar,which also serves to cause the adj ustment of the ribbon to its initialposition.

I claim as my invention:

1. The combination with the case A, provided with the openings 0, d ande, the rolls E, F and I, provided with the ratchet wheels 9, p and w,respectively, the spring actuated roll H, and the ribbon G, of theoperating bar D, provided with the catches 71, 4' and Z, for operatingthe rolls E, F and I, substantially as described.

2. The combination with the spring actuated roll H, the roll I, ratchetwheel w, pawl 00, and ribbon G, of the operating bar D, provided withthe catch I, adapted to turn the ratchet wheel 10 in one direction, andthe engaging lip a, adapted to raise the pawl as, to allow the unwindingof the ribbon from the roll I, substantially as described.

3. The combination with the roll E, provided with the ratchet wheel g,and the roll F, provided with the ratchet wheel 1), of the operating barD, provided with the catch 1', for operating upon the ratchet wheel g ofthe roll E, and the catch 0', for operating upon the ratchet wheel 19 ofthe roll F, upon a special movement of the bar D from its normalposition, substantially as described.

4. The combination with the roll F, provided with the ratchet wheel 13,the spring actuated roll 11, the roll I provided with the ratchet wheel10, and the pawl 00, of the operating bar D, provided with a catch Zadapted to operate the roll I upon the normal movement of the said bar,and with a catch 0, adapted to operate the roll F upon a specialmovement of the said bar from its normal position, substantially asdescribed.
